I have a wireless pair of headphones and I have it connected to my playbook via a dongle to the headphone slot.

I want to know if there exists a remote controller than can switch music tracks without me having to pull out my playbook? I usually keep the playbook in a backpack. In a perfect case it would be a bluetooth mini media remote control.

I have seen some mini blue tooth keyboards such as the hipstreet that advertises playbook comparable for under 40. Does any one know of anything more portable/ maybe cheaper?
